This invention relates to window sasheshaving ventilatorsbuilt therein and -has for its object, a particularly simple and efficient ventilator by which dust is excluded at all times from entering the interior sash member either when the ventilator isopened H slidablyiits in the sash member 2' and slides or closed. Y H y It furtherha s for its object ajparticularly simple, efficient and economical construction by which the ventilator is assembled in the sash member. s V Q The invention'consists in the novel features and in the combinations and the constructions hereinafter set forth and described.

In describing this invention reference is had to the accompanying drawings in which like characters designate corresponding parts in allthe views.

Figures 1 and QIare fragmentary views lustrating a sash in opposite elevations.

Figure-3 is a sectional view on line 3 3; Figure 1.

Figures tand 5 are opposite side eleva. tions'of the detached ventilator member, partly broken away. 7 c I Figure 6 is an end, elevation of the de-. tached ventilator member.

This invention comprises a window sash having a hollow sash member-as a'hollow bottom rail [formed with openings in its opposite walls and a ventilator member slidf able in the hollow sash member and'haw ing openings therethrou'gh movable into and out of register with the openings in the'con-i tiguous walls of the sash. member and also having a screen wh1ch is carried by the ventilatormember and moves therewith and which covers said openings at the outer side of the sash member whereby the openings are covered at all times by the screen. V

I 1 designates the sash and 2 the bottom rail which is usually formed up of sheet metal to have opposing walls 3 which are formed with ventilator openings or slots at therethrough,

Y the'bottom rail being formed with "a reentrant groove 5 along one edge for receiving the margin of the glass pane 6.- The rail 2 is here shown as in inverted U shapein general form" with its lower edges turned into form flanges at -7 for interlocking with a weather strip or buffer 8. Preferably the bottom rail also has an internal strip 9 extending lengthwise thereof near its lower edge and forming a guide for the ventilator member to be presently described. t

-10 designates the ventilator member which along the strip 9, it havin'g'a wall movable along the inner face of one of the'oppo sing walls of the sash member and formed with openings therethrough which are movable into and out of register with the openings 4 in the contiguous wall of the sash member.

11 is the screen which is carried by the sllding ventilator member covering the openmgs therethrough. The ventilator member is also formed with a flange which extends into one ofthe spaces at entrant groove 5. 7

Inthe illustrated embodiment of my inventhe side of the retion, the ventilator member is ofdouble'conv spaceson opposite sides of the reentrant groove 5. The walls 12 are formed with openings l4 therethrough movable into and out of register with the openings 4 in the walls 3 of the sash member; The. screen 11 is'carried on the inner side of one of the walls to cover theopenings therein and this screen is preferably located toward the outer side of the sash in order to not onlyexclud'e the'dust from entering thecalr but also from entering thehollow sash member. openings toward the outer sideof the sash have been open and the screen covered only the openings on the inside of'the sash and hence the hollow sash member filled up with dust, snow, etc., oftentimes pre'ventingthe operation of the ventilator. f I

The opposing walls 12 constitute two spaced apart members positioned in the bottom rail against-the walls of thebottom'l rail and provided with openings therein for registration with the openings in the walls ofthe rail. The intermediate part or bottom "wail of thejboxlike structure provides one means for maintaining the opposing walls orspac ed Heretofore, the

apart members in properly spaced relation. Also, the flanges or margins 13 which extend into the spaces on opposite sides of the reentrant groove 5 constitute another means for maintaining the opposing walls or members 12 in properly spaced relation.

Preferably in order to hold the ventilator member from rattling, it is provided with a spring runner 15 along the edge thereof contiguous to the strip 9, this runner being here shown as a leaf spring secured between its ends to the ventilator member, the end portions of the spring flaring outwardly. By reason of the arrangement of the spring, the ventilator slides evenly without binding.

The spring runner 15 constitutes means carried by the ventilator member 10 forholding the ventilator member 10 against rattling by pressing it edgewise in a direction at an angle to its sliding movement, and holding the margins 13 in the grooves or spaces at opposite sides of the reentrant groove 5. Each margin or flange 18 and the space in which it is located constitute in effect a coacting tongue and groove extending lengthwise of the ventilator member.

The ventilator member is operated by a handle 16 located on the inside of the sash and having a stem 17 extending through a lengthwise slot 18 in the inner wall 3 of the sash member or bottom rail and threading into the ventilator member or a block therein.

Owing to the arrangement of the screen and to the fact that it is part of the ventilator member and slides therewith, the openings on the outer side of the sash member, as well as on the inner side, are always protected against the passing of dust, snow, etc., therethrough. The fitting of the flanges of the ventilator member into the spaces at one or both sides of the re-entrant groove of the sash and the sliding of this ventilator member on the bottom strip of the sash provides a particularly simple and inexpensive assembly of the sash and the ventilator member.
